Histopathology and immunohistochemistry in a nonimmunized, infected mouse (A to C) and an immunized and challenged mouse (D to F). (A and D) Representative stainings with hematoxylin-eosin of a nonimmunized, infected mouse (A) and an immunized and challenged mouse (D). (B and E) Staining of B cells with anti-B220 antibodies in a nonimmunized, infected mouse (B) and an immunized and challenged mouse (E). B lymphocytes assembled mainly in follicle-like aggregates, and only a few were detectable in more luminal areas of the mucosa. (C and F) Staining of T cells with anti-CD3 antibodies in a nonimmunized, infected mouse (C) and an immunized and challenged mouse (F). In contrast to B cells, T cells were detected predominantly in the upper parts of the mucosa between gastric foveoli and glands. Magnification, ×10.
